Re: [xwiki-users] Page Loading Optimization
Hi Thibaut, Some useful Web Performance resources: 1) Steve Souders, /High Performance Web Sites: Essential Knowledge for Front-End Engineers/: http://www.amazon.com/High-Performance-Web-Sites-Essential/dp/0596529309/ref=pd_sim_b_1 Presentation of the 14 original rules upon which YSlow! was build on. Since then, a lot of new rules were added to YSlow! and Steve Souders moved from Yahoo! to Google and started working on Page Speed http://code.google.com/speed/page-speed/index.html 2) volume 2 /Even Faster Web Sites: Performance Best Practices for Web Developers/ by Steve Souders just came out: http://www.amazon.com/Even-Faster-Web-Sites-Performance/dp/0596522304/ref=sr_1_1?ie=UTF8s=booksqid=1257500156sr=8-1 Another 14 rules and tips which focus a mainly on Javascript optimization techniques. 3) http://www.stevesouders.com/blog/ Oana Thibaut Camberlin wrote: Hi all, Page Loading time is a very important criteria when developing a web site. According to a recent surveyhttp://www.webdesignerwall.com/general/users-place-more-weight-on-design/more than half people would drive away from a site with slow loading pages. There are several interesting issues that could be implemented to substantially improve page loading time in XWiki. Number one is aggreation of CSS and JS files in order to reduce HTTP requests. (For info, we have a total of 25 external CSS and JS files on a basic XWiki install when in the best world we would have just 2 - 1 CSS and 1 JS) Someone interrested in working on this with me ? ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
